Meaning

noun cases used to carry belongings when traveling

noun a worthless or immoral woman

noun the portable equipment and supplies of an army

originFrom Middle English bagage, from Old French bagage, baguage, from bague (“bundle, sack”), of Germanic/North Germanic origin, probably from the same ultimate source as Old Norse baggi (“pack, bundle”). Compare also bag. By surface analysis, bag + -age. The old meaning of "nasty woman" likely derives from the sense of "something awkward to be carried" (compare faggot).
